Portion of shoe sole



FIG. 1 is a bottom perspective view of a portion of shoe sole showing our new design; the black irregular outline being understood to represent a boundary between claimed and unclaimed subject matter, but not forming a part of the design;

FIG. 2 is an enlarged fragmentary perspective view of a portion of FIG. 1 showing the details of the traction cleats;

FIG. 3 is a bottom plan view of FIG. 2; and,

FIG. 4 is a right side elevational view of FIG. 3, the left side being a mirror image.

The fine, uneven broken lines showing the remainder of the shoe in FIG. 1; and the broken lines in the enlarged fragmentary views, illustrate the environment in which the design resides, but forms no part of the claim. 

The ornamental design for a portion of shoe sole, as shown and described.
